This paper presents the results of a research program conducted to design the all-weld metal deposited with AWS A5.5-81 E10018M, E11018M and E12018M SMAW-type electrodes. The role that different alloying elements such as manganese, carbon and chromium play on the tensile properties, hardness and toughness as well as on the microstructure was studied. Criteria for selecting the weld metal composition leading to optimum combination of tensile strength and toughness are suggested. The effect of the variation of heat input, within the requirements of the AWS standard, on the mentioned properties was also analyzed. It was found that the E11018M and E12018M all-weld-metal tensile properties are very sensitive to variations in heat input. For certain values of chemical composition, welding parameter ranges suitable to guarantee the fulfillment of AWS requirements were determined.
